Prospects for TTV Detection and Dynamical Constraints with TESS
Sam Hadden, Thomas Barclay, Matthew J. Payne +1
We consider the potential for the Transiting Exoplanet Survey Satellite (TESS) to detect transit timing variations (TTVs) during both its nominal and extended mission phases. Build…
Prospects for Refining Kepler TTV Masses using TESS Observations
Max Goldberg, Sam Hadden, Matthew J. Payne +1
In this paper we investigate systems previously identified to exhibit transit timing variations (TTVs) in Kepler data, with the goal of predicting the expected improvements to the…
A Compact Multi-Planet System With A Significantly Misaligned Ultra Short Period Planet
Joseph E. Rodriguez, Juliette C. Becker, Jason D. Eastman +20
We report the discovery of a compact multi-planet system orbiting the relatively nearby (78pc) and bright () K-star, K2-266 (EPIC248435473). We identify up to six possible p…
The Secular Dynamics of TNOs and Planet Nine Interactions
Gongjie Li, Samuel Hadden, Matthew Payne +1
The existence of Planet Nine has been suggested to explain the pericenter clustering of extreme trans-Neptunian objects (TNOs). However, the underlying dynamics involving Planet Ni…
A Criterion for the Onset of Chaos in Systems of Two Eccentric Planets
Sam Hadden, Yoram Lithwick
We derive a criterion for the onset of chaos in systems consisting of two massive, eccentric, coplanar planets. Given the planets' masses and separation, the criterion predicts the…
